insens350 [35]

Answer:

67

Step-by-step explanation:

To round 67.498 to the nearest whole number consider the tenths’ value of 67.498, which is 4 and less than 5. Therefore, we have to round down: the whole number ones place value of 67.498, 67, remains 67, and the decimal point and all digits (.498) are removed.

We learned in Chapter 13, Exercise 35 that the Paralyzed Veterans of America recently sent letters to a random sample of 100,000

Olegator [25]

Answer:

Step-by-step explanation:

given that the Paralyzed Veterans of America recently sent letters to a random sample of 100,000 potential donors and received 4781 donations

$H_0: p = 0.05\\H_a: p$

(left tailed test)

Sample proportion = $\frac{4781}{100000} \\=0.04781$

p difference = -0.00219

Assuming H0 to be true, std error of proportion

= $\sqrt{\frac{pq}{n} } \\=0.00158$

Test statistic Z = p diff/std error = -1.38641

p value = 0.0828

since p value >0.05 our significance level

we accept null hypothesis

There is no statistical evidence of a real drop in the contribution rate.
